DSNI090I subsystem-id DSNILGRT -STARTING ASYNCHRONOUS LOG READER TASK FOR SESSION ID session-ID LOCATION location CORR-ID corr-id STARTING AT startLRSN WITH numQualifiers QUALIFIERS

Explanation

An asynchronous task (SRB) for reading Db2 logs has started. This message provides the following information:

subsystem-id

The Db2 subsystem identifier.

session-ID

The unique session ID that identifies the log reading task.

location

The name of the IBM® Db2 Analytics Accelerator for z/OS® or the IBM Db2 for z/OS Data Gate instance that initiated the asynchronous log reader task. If the name is not available due to a transmission error, location will show the IP address of the remote requester.

corr-id

The correlation ID that identifies the system task. corr-ID starts with 014.LGRTSK and is appended with a 2-digit number to make it unique. This correlation ID can also be seen in lock timeout and dead lock messages (DSNT375I and DSNT376I) and can help identify which Integrated Synchronization connection was involved in the lock situation.

startLRSN

The position within the log at which the log reading task starts reading the log.

numQualifiers

To reduce the volume of data that is transferred when Db2 log records are replicated to an accelerator, unnecessary records are excluded through the use of a filter. The numQualifiers value indicates number of tables that are being filtered for the log reading process. This value can be higher than the number of tables that are enabled for replication to accommodate internal processes.
